The warrant position in Archer Aviation (ACHR) is in focus after the New York Stock Exchange halted trading in ACHR WS on September 1, 2026, citing Section 802.01D of its Listed Company Manual. Trading stays suspended until NYSE pulls warrant trading off the tape entirely before the open on September 15, with the hard expiration set for 5:00 p.m. New York City time on September 16. Any warrants still unexercised at that hour expire and become void, with holders carrying no further rights.
The warrant structure
Each ACHR WS warrant entitles the holder to buy one share of Archer's Class A common stock at an exercise price of $11.50. The agreement behind these warrants dates to October 27, 2020, originally executed between Atlas Crest Investment Corp., Archer's SPAC predecessor, and Continental Stock Transfer & Trust Company as warrant agent. Archer Aviation succeeded Atlas Crest under that agreement.
Archer flagged the approaching expiration in its second-quarter 10-Q for the period ended June 30, 2026. The September 4 8-K, signed by Chief Strategy Officer Eric Lentell at the company's San Jose headquarters, 190 West Tasman Drive, serves as the formal SEC notice ahead of the final window.
What to watch
The expiration closes the conversion path at $11.50 per warrant. Any Class A shares that could have been created through exercise are not issued if holders let the deadline pass.
Archer's Class A common stock continues to trade on the NYSE under ACHR, unaffected by the warrant halt. The halt covers ACHR WS only. The next confirmed event is the NYSE open on September 15, when warrant trading suspends. After 5:00 p.m. on September 16, the warrant position in ACHR WS is gone.
